PRINTING APPARATUS.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed February 4:. 1907. Serial No. 355.591.

T 0 all whom it may concern: I Be it known that I, MIonAEL MoMAnoN, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Printing Apparatus; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to printing apparatus of the class particularly designed for the printing. of cloth, paper, bags, paper or Wooden box covers, or the like; and has this class, which is small, simple and of economical construction and intended more parthem to stamp their business cards or other desired matter on the paper bags or covers of boxes employed in their business.

The operation, construction, and arrangement of the parts of the invention are fully described in the following specification and illustrated in the accompanying drawings, in which,-' 1

Figure 1 is a front elevation of the apparatus embodying the invention with the hood removed. Fig. 2 is a vertical trzlr ns- 1g. 3 is a section of the upper portion of the frame with the adjustable bearing plate swung in inoperative position, and Fig. 4 is a top plan view of one of the platen-roll supports.

Referring to the drawings, 1 1 designate spaced standards 01' uprights, which have their upper ends connected by a horizontal member 2 and their lower ends secured to a base member 3 or other suitable object.

Suspended from the connecting member 2 of the frame by bolts 4, or in any other suitable manner, is an inverted U-shape frame 5, the pendent arms of which constitute bearing-brackets for the coacting type-roll 6 and provided with the angled bearing slots 8 for removably receiving the trunnions of the inking-cylinder and with the axially alining bearing-apertures 9 for receiving the shaft 10 to which the type-roll 6 is secured by pins 10 The ends of the shaft 10 are preferably extended beyond the bearing-arms 5 and suitably'journaled in the contiguous frame standards 1 1, and one end is provided without its standard with a crank-arm 11' to facilitate a turning thereof. The type-roll 6 has the die-plate 12 secured to one side thereof and its opposite side cut away as at 13, to form a cam-shaped roll, substantially as shown.

Rising from the base 3 beneath the typeroll 6 are the two upright or vertical arms 14 14, which have their upper ends turned outwardly to form shelves l5 and slotted, as at 16, to permit the trunnions of a platen or impression-roll 17 to be removably dropped therein, said roll being supported in suitable position for its circumference to contact with the die-plate 12 of the roll 6 when the latter is revolved. In order to rovide a yielding bearing for the platen-roll 17 its trunnions are supported by slotted bearing-blocks 18, which are slidingly carried by bolts or pins 19 beneath the shelves 15 'of the uprights 14, and are normally retained in yielding contact with said shelves by the action of the coiled compressionsprings 20, which are supported below the blocks 18 by a followerplate 21, also carried by the bolts or pins 19. The tension of each set of springs 20 is regulated by an adj Listing-screw 22 which is centrally threaded through a plate 23 carried at the lower ends of the associated bolts or pins 19, and has its upper or inner end centrally abutting the under side of the followerlate 21, so that a turning of theIscrew will eflect a raising or lowering of the plate 21 as the thickness of the work to be'printcd and the impression to be given may require.

24 designates a bearing-plate which is adjustably secured to the outer side of each pendent arm of the bearing frame 5 by a bolt 25 (passing through an aperture in the arm an longitudinal slot 26 in the plate and carrying a winged nut at its outer end, This plate has its upper end slotted and one side of the slot partially cut away, as at 27, to register with the angled slot 8 of the arm, and its lower end slotted, as at 28, to adapt it to freely straddle the shaft 10, as shown in Fig. 2. The purpose of this plate is to compensate for any wear which may take place in the associated bearing-apertures 9 of the pendent arm, as the plate can be adjusted vertically to take up the wear, thus preventing a jumping of the type-roll as it has contact with the impression-cylinder when turned.

A hood 29 is shown as being suspended from the frame member 2 for protecting the inking-cylinder and type-roll, and has one side hinged, as at 30, to facilitate the removal of said cylinder and roll.

The operation of the apparatus is. as follows :After the tension of the springs 20 has been adjusted to suit the nature of the work and the impression desired, the article to be printed, whether it be a sheet of paper, a paper-bag, a wooden .or a paste-board bO-X- cover, is. placed on the upper surface of the impression-roll 17 within the opening formed between it and the type-roll by the cutaway portion 13 of the latter. This being done the crank-arm 11 is given a turn and the type-roll thereby caused to revolve so that the die-plate 12 thereon, which is inked by the inkingcylinder 7, comes in contact with the work and leaves the desired impression thereon. During the printing the operator may either retain hold of the article and withdraw it' from the same side of the apparatus. in which it is fed as soon as the type roll has revolved sufficiently to release it, or it may be permitted to pass through and be taken from the opposite side of the apparatus. Should it be desired to stamp the covers of-paste-board boxes or other articles having a depending marginal flange, an impiession-roll of suitable width for its impression surface tofit within the cover or other article between the side flanges thereof is em ployed.

Having thus described my invention, what I claim asnew, and desire to secure by Lette-rs Patent, is,

1. In a printing apparatus, a. pair of up right members having their upper ends each formed with a lateral projection and longitudinally slotted, bearing members yieldingly carried by said, projections, means for adjusting the yieldability of said bearing-members, and an impression-roll supported by said bearings, and a type-roll for co acting with the impressionroll.

2. In combination an inverted U-shaped standard, arms pendently secured to the loop portion of the standard and provided with two sets of bearings, an inking-roll mounted in one of said sets of bearings and a type- I cylinder in the other of said sets, said cylinder having one side partially cut away,

means for revolving the type cylinder, upright bearing standards disposed intermediate the legs of the main standard, and an impression roll yieldingly mounted in said upright standards beneath the type-cylinder.

3. In combination, a base, an inverted U-shaped standard rising from the base,

bearing arms pendently carried by the loop of the standard, a shaft journaled in said arms and the legs of the standard, a crank carried by said shaft, a type-cylinder mounted on the shaft between said arms, an inking-roll journaled in, the arms above the type-cylinder, bearing-arms. rising from the base intermediate the legs of the standard and having their upper ends turned outwardly to form shelves, bearings yieldingly suspended from said shelves, and an impression-roll journaled in said bearings, substantially as described.

4. In combination, abase, a bearing frame rising from thebase,,an inking-roll and a type cylinder journaled in said frame, means. for rotating the cylinder, arms rising from the base beneath the bearing-frame and having their upper end portions longitudinally sl0tted and bent outwardly at a point intermediate the ends of the slots,.bearings yieldingly carried at the under sides. of the outwardly turned portions of the arms, and an impression-roll having its. trunnions supported by said bearings. and permitted to be freely raised therefrom through the slots in the arms.

5. The combination with, the type-cylinder, of subjacent bearing-standards having their upper end portions longitudinally slotted and bent outwardly at. points. interme-' diate the ends of the slots to form shelves, pins pendently carried by said;shelves.,.spring 20 and plates 21 and 23 carried by said pins, bearing-blocks yieldingly supported beneath said shelves by the springs: 20,. adjustingscrews threaded to-the plates 23-and coacting with the plates 21 toadjust the tension of the springs, and an impression roll having-its trunnions projecting through. the slots in the MICHAEL MGMAHON.
